Ocean acidification strips seawater of the materials that marine animals such as corals plankton and shellfish use to build their shells and skeletons.

. In a dire climate warning scientists said that such quick acidification kills marine animals and even cause mass. Museum palaeontologist Prof Richard Twitchett explains Ocean acidification is a change in the pH of seawater which is normally around neutral. The term Ocean Acidification is new but the concept has been recognized for. This can stunt growth or cause.

Thus ocean acidification not only reduces surface ocean pH but also reduces the availability of carbonate ion. Like global warming this phenomenon which is known as ocean acidification is a direct consequence of increasing levels of carbon dioxide CO 2 in Earths atmosphere. Arctic Oceans waters are becoming increasingly acidic. Although it is unlikely that the ocean will ever become actual acid fall below a pH of 70 the term acidification refers to the process of the oceans becoming more acidic.

Ocean acidification is driven by increasing carbon dioxide in the atmosphere. It is the long-term change in seawater chemistry due to the absorption of. Ocean acidification is a complex issue that is being studied and addressed from several viewpoints in various locations and for different issues. This leads to a lowering of the waters pH making the ocean more acidic.

In the ocean the. The pH scale measures a substances. Ocean acidification means a significant reduction in the pH level of the ocean over an extended course of time caused principally by the uptake of carbon dioxide CO 2 from the atmosphere. Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean.

As the United Nations Development Programme UNDP itself points out in an article this has its. Currently about a third of the increase in atmospheric carbon dioxide is absorbed by the ocean. Ocean acidification has become a threat just in the two hundred years or so since the advent of the Industrial Revolution and there is strong evidence it is a direct result of human activity. As CO 2 dissolves in seawater it forms carbonic.

Ocean acidification The ocean absorbs around 30 of carbon dioxide CO 2 released to the atmosphere as a result of human activities. A consequence of the. Ocean acidification occurs when through a set of chemical reactions seawater absorbs CO2.
